There are fans, and then there are fans. Allen Pan falls into the latter category. This Zelda fan built a Raspberry Pi-based automated home system that allows him to control his entire house with an ocarina, the ancient wind-powered musical instrument used in the game.
Watch Pan demonstrate how his ocarina-controlled system operates in the video below, which is provided by Sufficiently Advanced/YouTube.
To make his system work, Pan used a Raspberry Pi, a $35 miniature computer, and a series of wirelessly connected microphones and sensors placed throughout his home. He then programmed the DIY system to respond to specific songs from the game "The Legend of Zelda: Ocarina of Time."
Now, as long as Pan has his ocarina with him and can remember the notes to each song, he can unlock the front door, find his cellphone, or learn the time. Some songs are even matched to the actions they trigger. If he plays "Song of the Sun" anywhere in the house, the lights turn on. "Bolero of Fire" turns up the heat. "Minuet of Forest" waters the plants. It's a unique way to bring a favorite video game to life.
